Purpose of Seal Water Line To Pump
Purpose of Seal Water Line To Pump
(OP)
As a piping estimator, I'm always interested in the purpose of equipment and general design in water and wastewater treatment plants. So this question is solely for my curiosity.
What is the purpose of a seal water line going into a pump casing? Does it fill some sort of diaphragm that seals in water? Does it ensure that the impeller cavity is completely full of water, so that air won't be trapped at start up?
Thanks for your time.

There is also new 'bell mouthed stuffing box' technology which eliminates the need as much for the flushing, and recirculates internally - clearly tappings and small pipework has smaller material thicknesses and so if priduct is corrosive, leakage can occur. it is referred to as API flushing plan 01
